Just did my front pass bearing and WOW did it make a difference. NOW that its much quieter I am hearing a grinding sound in the rear pass. Not to mention I just also replaced my sparky's and my CEL is back on with a rough idle that wont go away... when it rains it... well you all know!

Is yours a 05 ?

Could be the o-rings between the intake manifold and TGV's. for the rough idle, if it happens when it's cold and damp.

Does the car run fine when its warmed up fully ? Mine began to stall after it was warmed up too.
